Lee, the celebrity chef and longtime partner of Gov. Andrew Cuomo, made the announcement on ABC’s “Good Morning America” Tuesday. She had been diagnosed with breast cancer earlier this year and underwent a double mastectomy. Cuomo took time off to be with Lee following her surgery.

Lee praised early detection in the interview, and said she was only in the early stages of cancer. She said she will continue working as an early-detection advocate and with various cancer foundations.
